Heavy Coma. Maybe. At least that is what we currently suspect it is.



Nothing unusual with fast lenses, but the degree here is quite a bit disturbing. And completely ruins the MTF results at the border and corner spots until around f/5.6



I contacted Sigma Germany about this issue yesterday, but haven't heard back, yet.



Apart from this issue, the 85/1.4 seems to be one heck of a lens.

Well, that lenstip review did mention quite heavy coma (worse than the Zeiss and Nikon wide open). So maybe what you see is normal <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/blink.gif' class='bbc_emoticon' alt=':blink:' />
